F-Secure component
ffsm32 on my computer makes it lag a lot because it consumes huge amounts of RAM (up to 100 MB)
  alca trazom  
It is the security suite offered by Charter Cable internet service. It didn't install correctly on another machine I have. The firewall bumped into something on my machine and it won't work correctly now. I use windows firewall and don't need the Charter firewall.
It takes up 99% cpu and 90+% ram bringing system toa complete stop. Uninstall f-secure in safe mode to fix
Installed when I Installed Shaw Secure F-secure
It's using 123MB RAM on my machine!

It eats up alot of processing power and RAM.
F-Secure component, consumes a lot of memory
It is a core component of the F-Secure Realtime Protection
F-Secure component-Shaw Secure2.0-security system file. Consumes huge amounts of memory!
  shaw user  
F-Secure, remove the whole program using safe mode and install a decent Anti virus such as Kaspersky or Nod32
Consume too much memory, i uninstall it and my comuter its running perfectly after
Verified: it is part of F-Secure security suite, located in the security suite folder. If it is located elsewhere, it may be a virus... In some PCs it may not work properly,especially if some other antivirus or firewall is running.

Ironically, F-Secure tattled on it's own fssm32.exe, asking me whether to allow or disallow. If it's located at "C:\Program Files\F-Secure\Anti-Virus", the file is genuine. Otherwise it's like an infection. Don't use the Charter branded version of F-Secure if you can avoid it. It's garbage. Buy the unbranded version directly from F-Secure, or use something else. Don't depend on Windows firewall. There's no anti-virus, and the firewall itself is riddled with holes.
also in charter security
Integral to F-secure firewall/antivirus. Charter Communications offers this security suite free to all its internet customers. This program does tend to use a lot of RAM and CPU at times thus hanging the computer occasionally
It's using more than 300MB RAM !!! and grows up
I got this when i installed the security program from Shaw Cable.
part of Embarq Online Sec Ste. takes alot of memory. Embarq rep said that it updates ste. I do it manually and use Win Firewall.
F-Secure / schlechte Software
This uses alot of cpu memory when scheduled scanning activates.Turn off scheduled scanning and this should fix the problem.
Part of F-Secure, which is also included in the Charter Security Suite. This file does use a lot of computer resources, but without this file the program will not function properly.

Vital F-Secure (virus protection software) component. Deletion means disabling the whole programme and leaving your computer unprotected against malware. It's basically as if you'd cut a hole into a condome before using it. Not exactly recommendable. The file needs a lot of RAM while it updates the virus definitions. It's just a few minutes, then you have your CPU almost to yourself again.

F-Secure's Scanner Manager
It's a vital tool of the F-Secure antivirus! Don't remove or if you wish to, install a new antivirus program right after the removal of F-Secure!
Yes i got it from Charter cable and it hogs up my pc every am
Part of TalkTalk security (powered by F-Secure)
Charter Security Suite / F-secure executable. Removing antivirus is not smart move, unless your computer is not on the Internet and you use only trusted software.

uses huge cpu 50% upwards and causes stalls

Use the 6resmon command to identify the processes that are causing your problem.
